Bruce Jenner appears in a second promo for his upcoming interview with Diane Sawyer. The interview is scheduled for April 24th on a special episode of 20/20. In this second promo–unlike the first one–Bruce Jenner speaks.

“My whole life has been getting me ready for this,” the Keeping Up With the Kardashians patriarch says in the promo.

“Bruce’s primary goal is to bring awareness to this issue in order to help others in the transgender community,” a source tells People of the upcoming interview.

Bruce Jenner “wants this to be taken seriously so that his situation can have the most positive impact on society’s perception of the transgender community,” the source adds.

Jenner is comforted by the support he receives from his family–sons Burt, Brandon, and Brody Jenner, and Kylie and Kendall Jenner–as well as stepdaughters Kourtney, Khloe, and Kim Kardashian.

“Everything is going great with the family,” Brody Jenner said during a recent interview.

“Everybody’s very happy. Everybody’s living life. And it’s a great time for all of us,” he added. “Everything’s really great.”
